摘要:
A positive electrode for a lithium-sulfur battery includes a positive active material including a sulfur-based compound, an electrically conductive material, an agent for increasing viscosity, and a binder. The agent is selected from a cellulose-based compound, an ionically conductive polymer, and a mixture thereof. The binder includes styrene-butadiene rubber.
摘要:
The present invention relates to a negative electrode for a lithium metal battery and a lithium metal battery comprising the same. The negative electrode of the present invention comprises a negative active material layer of metallic lithium or a lithium alloy, and a passivation layer formed on the negative active material layer. The passivation layer has a structure comprising a 3-dimensionally cross-linked polymer network matrix penetrated by linear polymers. The passivation layer formed on the surface of the negative electrode reduces reactivity of the negative electrode and stabilizes the surface, so that it offers a lithium metal battery having superior life cycle characteristics.
摘要:
A positive active material for a rechargeable lithium-sulfur battery includes a core of a sulfur compound and a surface-passivation layer formed on the core. The surface-passivation layer is made of a coating-element-included compound selected from the group consisting of a coating-element-included hydroxide, a coating-element-included oxyhydroxide, a coating-element-included oxycarbonate, a coating-element-included hydroxycarbonate, a mixture thereof.
